Answer:
c) formal power
Step-by-step explanation:
Formal power is simply power or authority that is officially given to a person due to his or her official title.
In this case, a specific person, the governor, is given his title by his electors, and one of the official powers the governor has is to represent the state at important ceremonies.
Another formal power that a governor has is the power to execute the state's laws, and spend the state's public resources. This is the executive power and is vastly more important than representing the state at important ceremonioes (both are forms of formal power though).
